THREE expressions equivalent to –81x+27.
loris [4]

Hey there!

One thing we can do to get an equivalent expression is to divide both sides by 3. That would get us \frac{-81x+27}{3}. If we simplify this, we get -27x+9.

Another thing we can do is divide both sides by 27, because it is divisible by 27. That would get us \frac{-81x+27}{21}. If we simplify this, we get -3x+1.

One last thing we can do is multiply it by 1, and add zero, because that does not change it at all. That would give us 1(-81x+27)+0.

Have a terrificly amazing day! :D
